ACTIVE-CHLORINE PREPARATION,

No Drawing.

This invention relates to' 'active chlorine preparations and methods ofmaking the same, and more particularly to an active chlorine preparationprovided with cineol for the purpose of imparting a distinctive flavorand odor and substantially masking the disagreeable odor of thechlorine.

An object of the invention is to provide a composition containing activechlorine and capable of use as a disinfectant and healing agent in whichthe disagreeable odor nor-.

mally present in a chlorine preparation is masked. I

A further object of the invention is the provision of a process ofpreparing an active chlorine preparation in which the odor of thechlorine 1s removed.

The principal difiiculty in overcoming the objectionable odor ofchlorine in active chlorine preparations is due to the fact that suchpreparations are deliberately used as deodorants and destroy mostodorous substances. It is therefore essential that the material used forthe purpose of masking the chlorine odor must be a substance having theproperty of being resistant to the destructive action of chlorinecompounds, and at the same time, capable of furnishing an odor andflavor-of its own which will do;

stroy or mask the chlorine odor and flavor of the compound. In thepreparation of such chlorine compounds it is the usual practice topreserve certain conditions of alkalinity and light exposure under whichstable compounds are obtained. This solutions of sodium hypochlorite inwater with sodium chloride and small quantities of sodium carbonate andcalcium salts, or solutions or sus ensions of organic chlorine compoundssuc as sodium paratoluenesulphonchloramide, known to the trade aschloramine-T or other organic substances which contain j activechlorine, have been employed. Such suspensions or solutions may,

the organic compounds, be neutral or slightly alkaline stearatesprepared in the form of Y cerates or creams for local application, or

solutions in a non-reducing solvent in. which the chlorine compound ispresent.

I have found that cineol, a substance ob tained from oil of eucalyptusand from other sources, imparts a distinctive odor and flavor to suchpreparations substantially masking 0 I 1 In the preparation of pastes orcreams'ot .the disagreeable odor due to the presence "chlorine withoutmaterlally reducing the active chlorine compound.

which has the formula C H O, may be added to the preparation in anysuitable manner to obtain a substance that may be applied or used insubstantially the same manner that similar active chlorine preparationsare now applied or used and substantially the same results may beobtained without the unpleasantness of the chlorine odor and flavor.

In the preparation of a cream or paste I heat 25 parts of stearic acid,2 parts of potassium hydroxid, and 73 parts of water in a steam jacketedvessel until a thick smooth cream or paste is obtained. This paste isthen cooled to a temperature of substantially 25 (1., and to 95 parts ofthe paste 5 parts of sodium paratoluenesulphonchloramide, or

other organic compound capable of yielding active chlorine and ermanentin slightly alkaline or neutral f aitty acid mixtures, is added. Themixture is then stirred to thoroughly mix it and .5 parts of cineoladded thereto. The cineol is thoroughly incorporated in the mixtureproducing a cream which is ready for use and may be packed incollapsible tubes of nonreducin material or other suitable containers.Suc a cream is effective in the treatment of ivy poisoning and has theadded advantage of the cooling I v roduced by the cineol which acts asan ad itional healin agent.

In the reparation of a fiavore solution .5 cc. of cineol is added to 100cc. of a solu- 1 bottles in a cool place. The solution is comparativelystable and tests show that when kept fora period of six months underproper conditions the chlorine content for 100 cc. showed a reductionfrom 1.045 grams at the beginning to 1.039 grams at the end of sixmonths. In such a solution the odor of chlorine is completely masked inthe original solution and lar ely so on dilution.

As. a further'modiiication sodium acetate in less than 5 per cent may beadded to such solution and this-increases, to some extent,

the amount of cineol that passes into solu tion and modifies the tasteof the preparation when diluted with water.

Stearicacid or similar nonreducin c material ma he employed alone to obtain apreparation which does not dissolve in water nor provide water solubleacidity which would liresil: up the chlorine compound.

While I have described in detail the preferred practice of my process,it is to be understood that the details of procedure and proportions ofingredients may be Widely varied, and that known chemical equivalentsmay he employed in place of the materials n'ientionedr without departingfrom the spirit of the invention or the scope of the suhjoined claims.

I. claim:

an active chlorilie-yielding material and rineol in a form adapted tomask the chlorine odor thereof.

2. A substantially stable chlorine composition of the characterdescribed comprising a major portion of an active chlorine material anda minor portion of cineol substantially free from modifying constituentsbut in an amount sufficient to mask the chlorine odor thereof.

3. A substantially stable chlo ne compound of the character described C(prising a Water soluble chlorine-yielding material, a soluble salt of analkaline earth retal, and cineol in a form adapted to mask the chlo rineodor of said chlorine-yielding material.

in testimony whereof I affix my signature.
